An ultra low power AlGaAs/InGaAs HJFET SCFL circuit for 10 Gbps applications with 1.3 V supply voltage

Abstract

SCF'L D-FFs with supply voltage as low as 1.3V are designed and fabricated. The supply voltage is decreased by optimizing the logic swing and the voltage shift in the source followers. The D-FFs, using 0.25 Fm AlGaAdInGaAs HJFETs, operate at up to 10 Gbps, with power consumption as low as 19 mW.
